Abstract
Oral squamous cell carcinoma (OSCC) is the most common malignancy among head and neck squamous cell carcinomas. Targeted therapy plays a crucial role in the treatment of OSCC. However, new and more targets are still needed to develop. Stanniocalcin-1 (STC-1) is a glycoprotein hormone that affects the progression of cancers. However, the potential role of STC-1 in OSCC progression remains to be explored. Here, we aimed to elucidate the role of STC-1 in OSCC. We revealed that STC-1 was highly expressed in OSCC tissues and is correlated with poor patient prognosis. Knockdown of STC-1 significantly suppressed the growth of OSCC cells and restrained glycolysis by reducing glucose consumption, ATP production, and lactate levels. Mechanistically, STC-1 ablation inhibited the PI3K/Akt pathway, reducing the phosphorylation levels of PI3K and Akt. In conclusion, STC-1 depletion restrained OSCC cell growth and glycolysis via PI3K/Akt pathway and has the potential to serve as a therapeutic target for OSCC.

Abstract
ABSTRACT Fatty acid synthase (FASN) is an essential molecule in lipid metabolic pathways, which are crucial for cancer-related studies. Recent studies have focused on a comprehensive understanding of the novel and important regulatory effects of FASN on malignant biological behavior and immune-cell infiltration, which are closely related to tumor occurrence and development, immune escape, and immune response. FASN-targeting antitumor treatment strategies are being developed. Therefore, in this review, we focused on the effects of FASN on tumor and immune-cell infiltration and reviewed the progress of related anti-tumor therapy development.

Abstract
PDZ and LIM domain protein 1 (PDLIM1) is a cytoskeletal protein and is associated with the malignant pathological features of several tumors. However, the prognostic value of PDLIM1 and the molecular mechanisms by which it is involved in the metabolism and progression in gastric cancer (GC) are still unclear. The GEPIA database was used to predict the expression and prognosis of PDLIM1 in GC. qRT-PCR and western blot assays were applied to detect the mRNA and protein expression in GC tissues and cells. Loss- and gain-of-function experiments were performed to evaluate the biological role of PDLIM1 in GC cells. The Warburg effect was detected by a battery of glycolytic indicators. The interaction of PDLIM1 and hexokinase 2 (HK2) was determined by a co-immunoprecipitation assay. Furthermore, the modulatory effects of PDLIM1 and HK2 on Wnt/β-catenin signaling were assessed. The results showed that PDLIM1 expression was upregulated in GC tissues and cells and was associated with a poor prognosis for GC patients. PDLIM1 inhibition reduced GC cell proliferation, migration and invasion and promoted cell apoptosis. In the glucose deprivation (GLU-D) condition, the PDLIM1 level was reduced and PDLIM1 overexpression led to an increase in glycolysis. Besides, mechanistic investigation showed that PDLIM1 interacted with HK2 to mediate biological behaviors and the glycolysis of GC through Wnt/β-catenin signaling under glucose deprivation. In conclusion, PDLIM1 interacts with HK2 to promote gastric cancer progression by enhancing the Warburg effect via Wnt/β-catenin signaling.

Abstract
Breast cancer (BC) is a malignant tumor that seriously endangers health in women. BC, like other cancers, is accompanied by metabolic reprogramming. Among energy metabolism-related pathways, BC exhibits enhanced glycolysis, tricarboxylic acid (TCA) cycle, pentose phosphate pathway (PPP), glutamate metabolism, and fatty acid metabolism activities. These pathways facilitate the proliferation, growth and migration of BC cells. The progression of BC is closely related to the alterations in the activity or expression level of several metabolic enzymes, which are regulated by the intrinsic factors such as the key signaling and transcription factors. The metabolic reprogramming in the progression of BC is attributed to the aberrant expression of the signaling and transcription factors associated with the energy metabolism pathways. Understanding the metabolic mechanisms underlying the development of BC will provide a druggable potential for BC treatment and drug discovery.

MEDICAL ONCOLOGY (NORTHWOOD, LONDON, ENGLAND) 2022; 40:5.

Abstract
Cerulenin is a fungal metabolite and a specific inhibitor of fatty acid synthase (FASN), which has shown a potential anticancer activity. 20-25% of breast cancer patients with ErbB2-overexpressing develop resistance to treatment. Therefore, it is urgent to find an effective new target for the treatment of ErbB2-overexpressing breast cancer. Our previous study found that cerulenin inhibits the glycolysis and migration of SK-BR-3 cells, but the effect of cerulenin on other malignant phenotypes of breast cancer is still unknown. Furthermore, the mechanism by which cerulenin displays its inhibitory effects is not fully understood. In this study, we systematically investigate the inhibitory effects of cerulenin on proliferation, migration, invasion and glycolysis of ErbB2-overexpressing breast cancer cells and its molecular mechanism. We found that cerulenin obviously suppresses the proliferation, migration, invasion as well as glycolysis. Through bioinformatic analyses, we found that PKM2 might be a target of cerulenin. In addition, ErbB2 and its signaling pathway upregulated PKM2 protein levels. Furthermore, we demonstrated that cerulenin downregulated the protein levels of ErbB2, PKM2 and EMT markers (MMP9, MMP2 and Snail2) in a dose- and time-dependent manner. Finally, the inhibitory of cerulenin on colony formation, migration, invasion and glycolysis, as well as protein levels of EMT markers were rescued by replenishing with PKM2. These findings illustrated that cerulenin inhibits proliferation, migration, invasion and glycolysis by targeting ErbB2/PKM2 pathway in ErbB2-overexpressing breast cancer cells.

[PMID: 33179541 PMCID: PMC7673061 DOI: 10.1177/0300060520970761] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Accepted: 10/12/2020] [Indexed: 12/12/2022] Open
Abstract
OBJECTIVE Ovarian cancer (OC) affects nearly 22,000 women annually in the United States and ranks fifth in cancer deaths, largely because of being diagnosed at an advanced stage. Autophagy is the cellular process of self-degrading damaged or degenerate proteins and organelles. Long non-coding RNAs (lncRNAs) are a group of RNA molecules whose transcripts are greater than 200 nt but are not translated into proteins. However, just a small number of autophagy-related lncRNAs have been explored in depth. METHODS We used RNA sequencing data from The Cancer Genome Atlas (TCGA) and autophagy datasets to identify dysfunctional autophagy-related lncRNAs and provide potential useful biomarkers for OC diagnosis and prognosis. RESULTS Seventeen differentially expressed lncRNAs (AC010186.3, AC006001.2, LBX2-AS1, SNHG17, AC011445.1, AC083880.1, MIR193BHG, AC025259.3, HCG14, AC007114.1, AC108673.2, USP30-AS1, AC010336.5, LINC01132, AC006333.2, LINC00665 and AC027348.1) were selected as independent prognostic factors for OC patients. Functional annotation of the data was performed through gene set enrichment analysis (GSEA). The results suggested that the high-risk group was mainly enriched in specific tumor-related and metabolism pathways. CONCLUSION Based on the online databases, we identified novel autophagy-related lncRNAs for the prognosis of ovarian cancer.
